	CREATE TABLE test
	(
	"v_date_old" TIMESTAMP,
	"v_varchar1_old" CHARACTER VARYING(10),
	"s_varchar_old" CHARACTER VARYING(10)
	)
	DISTRIBUTED BY ("s_varchar_old");
	insert into test values ('2012-03-16 00:00:00', NULL, 'IR$6D');
	EXPLAIN UPDATE test SET v_varchar1_old = s_varchar_old;
	
	Objective : Since we are not updating the distribution column, we don't need a Redistribute Motion.

	Update  (cost=0.00..431.09 rows=1 width=1)
   	->  Result  (cost=0.00..431.00 rows=1 width=34)
        	 ->  Split  (cost=0.00..431.00 rows=1 width=28)
               		->  Table Scan on test  (cost=0.00..431.00 rows=1 width=24)
